Resetting the ECU on a Citroen C3

Model: Citroen C3 FC, FN - Years 2002-2009
Part: Warning light – error code

To reset the ECU on a Citroen C3, follow this very simple procedure. Turn off the engine, pull the handbrake, and remove the key. Open the bonnet and place the support rod. At this point, locate the ECU (see video), and simply disconnect the battery by unscrewing the terminals, then disconnect all three connectors that go to the ECU itself. This will completely power down the ECU. Wait a few minutes and reconnect everything. Check that all the car's controls are functioning correctly.
